Application filed September 12, 19.12. Serial No. 719,957.

lTo all whom it mag/concern porcelain post on its way from thelongitudinal thread passage of the shuttle to the` eye thereof.`

The present improvement is illustrated in the accompanying drawings,wherein- Figure l, is a plan view of the eye end of the shuttle, aportion being broken away to aid in the illustration. Fig. 2, is asimilar view showing the improved portions in horizontal section. Fig.3, is a side view of the shuttle looking toward the shuttle eye andparts being broken away and shown in vertical section. Fig. 4,. isatransversesection in the plane indicated by the line 4--4 in Fig'l. Fig.5, is a perspective View of the sheet-metal threading device, partsbeing broken away, and of the porcelain snub.- bing post usedtherewith.: Fig. 6, is a detail view ofthe holder for said porcelainsnubbing post removed from the sheet-metal,

threading device.

As shown in the-drawings, A, is the shuttle having a slotted side-eye B,in 'one side, and C, is the sheet-metal threading device which issubstantially like t at shownl in 'the-United States-Letters Pat nt ofStimpson, No.'933,497, and which has a longitudinal .thread passage a,through which the thread passes on its way from the weft-4 carrierwithinthe shuttle to the eye B. The thread eye B, is guarded at frontand back -by means of hollow porcelain snubbing posts, D, and E, overwhich the thread runs as the shuttle travels in its different flights.There is a third porcelain snubbing post F, at the -juncture betweentheA longitudinal thread passage a, and the eye B, over which .thethread runs whichever way,k the shuttle travels. These snubbing postsare madecf vitreous material, such as porcelain, which withstands thewear incident to the employment of worsted or similar rough yarns. Theseporcelain posts are hollow cylinders,

' because the hollow form facilitates replacement when needed.

In the respects thus` far described the shuttle is ysimilar tothat`disclosed in Letters I atent of the United States of John F.ONeill, No. 1,064,245, granted June 10,1913.

The present improvement consists in the means employed for holding theporcelain post F, in position. For this purpose there 1s provided asheet-metal holder G, which 1s a cylindrical sheet-metal tube, open atits bottom for the insertion of the post F. At its middle this holder iscut away as shown at b, so as to expose the post F, in the path itsupper en d which fits over a depending flange e, of the sheet-metalthreading device and which aids in positioning the holder firmly securedto the sheet-metal threading device by means of solder f, along thecontiguous surfaces.

The porcelain post F, tits snugly within the holder G, and,consequently, when the holder isfastened to the sheet-metal threadingdevice and the porcelain post is in place, all can be handled andassembled in the shuttle as a single part. When the threading devicewith the holder G., and post F, is placed within the shuttle the post F,is maintained securely in place since it cannot move downwardly becauseits lower end is substantially 'flush with the lower end of the holderG, and hence just above the Hoor of the passage a, constituted by thewooden body of the shuttle; and itcannot move upwardly because seatingagainst the flange e, of the sheet-metal threading device.

placed in case of need by simply removing the sheet-metal threadingdevice from the shuttle and taking out the old post and replacing it bya new one.
